Large-scale open online courses are based on connectionism theory and open teaching of online learning, which are different from traditional universities. The scope of the course not only covers a wide range of scientific and technological disciplines, such as mathematics, statistics, calculation and so on.

The significance of studying hard is as follows:

1. Learning can make us rich. Learning can make us earn more money, because you have knowledge that others don't. Knowledge can be turned into wealth. Different occupations will get different money because of the different level of knowledge they need. Your knowledge will be returned to you in the form of money.

2. Learning can improve our temperament. When we describe a person's temperament, we often say that "there is a poetic soul in the belly." A knowledgeable person will bring his own literati temperament, which can be seen from his words and deeds, every move and so on. Therefore, learning can subtly change our temperament and improve our self-cultivation.

3. Learning can make us think deeply. The process of learning is also the process of thinking. Thinking more and using more brains can not only make us smart, but also make our thoughts profound. Thought can change the world, and it can also change ourselves. Thought can make us understand things better.

4. Learning can broaden our horizons. Learning can let us know what we didn't know before and open the door to a new world for us. Knowing what we can't see in our daily life, but what really exists, is just like the universe. After learning, we found that the sky is much wider than we thought.

5. Learning can enhance personal value. Learning is a process of constantly improving self-ability. It can also enhance self-worth. The embodiment of self-worth is to see how many people you can influence. The more knowledge you learn, the more people you influence and the more you realize your own value. The value of human life is the embodiment of personal value.

6. Learning can make our hearts calm. Learning to read, think and explore can make me feel much calmer. Only by calming down can we better feel the meaning and value of life and achieve the great realm and spirit of "not rejoicing in things, not being sad for ourselves". Only with inner peace can we be calm and humble in the face of all hardships.

7. Learning can change the way we look at things. Learning allows us to observe the world from another angle. Learning is the process of communicating with people who are better than us. We can get their opinions from them, and then under their guidance, we can change the original perspective of looking at things and look at the problem from another angle in essence.
